Itanistomig
Based on 1 Customer Validation
Itanistomig (LB-101) is a tetravalent bispecific antibody targeting PD-L1 and CD47. Itanistomig blocks PD-L1 and achieves tumor enrichment through binding to PD-L1, and also exerts conditional CD47 blocking activity via cleavage of the hinge linker in the PD-L1-positive tumor microenvironment. Itanistomig induces antibody-dependent cellular phagocytosis in human CD14+ cells and drives tumor regression. Itanistomig can be used in research related to solid tumors.

Flow cytometric analysis of 1X106 Jurkat cells labeling CD274 with Itanistomig (HY-P991004, red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. AF488-conjugated Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa Isotype Control (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
